Part 4: ESC press release roundup

Finally, in case you missed any of the many announcements of products, services, and partnerships relating to Embedded Linux that accompanied the conference, here's a list of all the headlines . . .

• ELC proposes unified Embedded Linux platform spec
• (more…)

Embedded systems, even in their high-end variants, are resource constraint systems by desktop or server standards. At the same time, complexity of operations require many optimization strategies that were designed for server and desktop systems to be utilized in embedded systems as well. (more…)

During the development of embedded GNU/Linux projects a few main modes of operation have evolved. These modes will be briefly described in the next sections, showing the flexibility of embedded GNU/Linux. This flexibility is a product of the wide range of hardware Linux and embedded Linux has been deployed on — ranging from commodity… (more…)

The term compatibility has been widely misused, OS's claiming to be 'compatible' as such — without stating to what they are compatible. So first a clarification as to how this term is being used here. Compatibility between embedded OS and desktop development systems is one aspect here, this compatibility being on the hardware and… (more…)

Q5. How does OSware compare with other dual-OS, telecom-oriented stuff, such as products from Enea or Wind River? (more…)

Q24. Can you characterize the state of embedded Linux, as a market and as a technology? (more…)

Sorry; this article is no longer available online at IT-Director.com… (more…)

D. SUMMARY

At this point, it does not appear that any one approach can be all things to all realtime applications. It is therefore too early to pick a winner. Advocates of a given approach are therefore advised to concentrate their energy on implementations of their favorite approach, rather than engaging in flamewars with advocates of other… (more…)

C. LINUX REALTIME APPROACHES

The following general approaches to Linux realtime have been proposed, along with many variations on each of these themes:

1. non-CONFIG_PREEMPT
2. CONFIG_PREEMPT
3. CONFIG_PREEMPT_RT
4. Nested OS
5. (more…)

B. DESIRABLE PROPERTIES

As usual, there are conflicting desires, at least they conflict given the current state of the art. These desires fall into the following categories:

1. Quality of service (more…)
